Improving the performance of indexes is really really hard. In this

I really don't think caching is a band-aid, it is a good solution.
Even
with optimised indexes, you will find that you need caching to get
reasonable performance if you have a catalog with close to a million
or
more documents indexed. Given a large enough catalog, I would argue
that
caching is equally as necessary as having a large cache for a ZEO
client.
But caches expire and results get invalidated, and therefor we should
continue to optimise indexes. With some help we should be able to
contribute at this level too.

Thanks to you and everyone else working on these sometimes thankless
performance improvements.
